After a thorough root cause analysis of this release, it was determined that the developers tended to incorrectly use ">" and "<" rather than the ">=" and " <= " in the code at several decision points.

This caused several borderline cases to be handled incorrectly.

Based on this analysis, how would you modify your test strategy for the next version's release?

AUse the same approach, but schedule 50% more time for regression testing

BCreate test cases using boundary value analysis techniques

CRe-analyze the test basis and create a state transition diagram to ensure all transitions are properly tested

DEnsure that decision tables are used throughout the testing process

Answer : B

Boundary value analysis is a technique that focuses on testing the values at the boundaries of valid and invalid partitions. It is suitable for testing the errors caused by incorrect use of relational operators in the code, such as ''>'' and ''<'' instead of ''>='' and ''<=''. By creating test cases using boundary value analysis, the tester can verify that the system handles the borderline cases correctly and does not miss any edge cases.

Question 4

You have been provided with the following decision table that was used for smoke testing the previous release of a set of hotel reservation software.

During discussions with the Test Manager you agreed that software behavior focused on the date of reservation, especially as midnight approaches, presented additonal risk.

You need to add more tests to provide more thorough coverage of the test conditions. Which of the following techniques should you use to design more tests?

AOrthogonal Arrays

BBoundary value analysis

CState transition

DPortability

Answer : C

State transition is a technique that analyzes the behavior of an application for different input conditions and how it changes from one state to another in response to events.It is useful for testing scenarios where the date of reservation is a critical factor that affects the system state and output1

Question 5

You have been working as a Test Analyst for a customer-facing application that is critical to the reputation of your company. You have worked with business users to create use

cases and captured a variety of scenarios, including both main and alternate paths. You have managed to create a suite of use cases that portrays a realistic usage model of the system.

Because of this, you will also be able to use these use cases for what other type of testing?

AExperience-based testing

BPerformance testing

CDefect-based testing

DFMEA

Answer : B

Use cases can be used for performance testing to measure the response time and throughput of the system under different workloads and scenarios. Use cases describe the process flows through the system based on its most likely use, which can help to simulate realistic user behavior and identify potential bottlenecks and performance issues.

Question 6

You have been assigned to test an application that allows users to conduct banking online. You have been asked to verify the various installation environments for the product. According to the specification the product supports four browsers (Edge, Chrome, FireFox and Safari), three operating systems (Windows, Mac, Unix), and four languages (English, Spanish, French, German). As you are reviewing the specifications you realize that the actual operating system names and versions were not included, only the major category. From this, you conclude that if you pick one from each of these sets (for example, select Windows 10 for the Windows OS), that testing should be sufficient.

You have researched the product and determined that there should be no interaction between these three characteristics that would affect the operation of the system. However, you do want to exercise representative set of these options while conducting the other functional testing for the product.

If you decide to test pairs of combinations, how many combinations will you need to test?

B12

C16

D48

Answer : B

Testing pairs of combinations is a technique that reduces the number of test cases by testing only two factors at a time, instead of testing all possible combinations. Testing pairs of combinations is based on the assumption that most defects are caused by interactions of at most two factors. Testing pairs of combinations can be applied to this problem using the installation environments, which are the browsers, the operating systems, and the languages. By using testing pairs of combinations, the number of test cases will be lower than exhaustive testing, which would require testing every combination of factors. The formula for calculating the number of test cases for testing pairs of combinations is:

N = P * (P - 1) / 2

where N is the number of test cases, and P is the number of values for each factor. In this problem, P is 4, as there are four browsers, four operating systems, and four languages. Therefore, the number of test cases for testing pairs of combinations is:

N = 4 * (4 - 1) / 2 N = 4 * 3 / 2 N = 12Reference=

Question 7

You are building tests using the classification tree below. You have been told that pairwise testing would be a good approach to this problem. When you apply the pairwise testing technique what would be the expected effect on the number of test cases?

APairwise testing will require fewer test cases than exhaustive testing

BPairwise testing will have no effect on the number of test cases

CPairwise testing would not be applicable for this problem

DPairwise testing would not be possible because equivalence partitions have not been defined

Answer : A

Pairwise testing is a technique that reduces the number of test cases by testing only pairs of values for each data item, instead of testing all possible combinations. Pairwise testing is based on the assumption that most defects are caused by interactions of at most two factors. Pairwise testing can be applied to this problem using the classification tree, which shows the data items and their values. By using pairwise testing, the number of test cases will be lower than exhaustive testing, which would require testing every combination of values for each data item.Reference=
